Answer:
It doesn't have a solution because if you try to graph each line y=5x+10 and y=5x-8, you will have a parallel line
Step-by-step explanation:
Answer:
We have a binomial probability distribution, in which:
P(X = 0) = 0.064
P(X = 1) = 0.288
P(X = 2) = 0.432
P(X = 3) = 0.216
Step-by-step explanation:
For each flight, there are only two possible outcomes. Either it is for domestic travel, or it is for international travel. Flights are independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Let x be the number of requests among the next three requests received that are for domestic flights.
3 flights, and 60% are for domestic travel. This means that . The probabilities are given by:
Answer:
56
Step-by-step explanation:
that is the procedure above
Not enough information. The question doesn't say how much one quart of paint covers.
EDIT: here's the solution
we have to find the total area of the 4 walls and subtract the area of the door. there are 2 walls with dimensions 16 by 10, and 2 walls with dimensions 16 by 12. so we have: 2(16*10)+2(16*12)=320+384=704 for the area of the walls. now, we can find the area of the door which is 3*8=24. <span>so we subtract the area of the door from the area of the walls, so we have: 704-24=680. </span><span>Since a quart of paint covers 100, then we divide and get 680/100=6.8 but since we need a whole number of quarts, we round up to get 7 quarts of paint. </span>
